Need Help with this question

Note: Triangle may not be drawn to scale.


Suppose a = 9 and b = 12.


Give each answer as a reduced improper fraction:


sin(A) =   


cos(A) =   


tan(A) =

So for this question consider the following definitions. c^2 = a^2 + b^2 sin(A) = a/c cos(A) = b/c tan(A) = a/b Using these definitions you will be able to solve the problem

tanA = 3/4


sinA = 3/5


cosA = 4/5


It's a 3-4-5 triangle inflated by a factor of 3 to get 9-12-15 sides. 15 is the hypotenuse = sqr(9^2+12^2) = sqr(81 +144) =sqr225 = 15


sinA = opposite side over adjacent = 9/15 = 3/5


cosA = adjacent side over opposite side = 12/15 = 4/5
